matically controlling the flow of lorhenting stand boilers, etc.

i The primary object is to improve and sunphi" the ('tlllfillfllttlfln,with the several parts so arranged as to apply the operating forcesdirectl) and without straining or cramping tendexngy. I Another ()l)JtCl is'to render the working valve to the hand adjustment disclosed inpatent to Lindlev Lawson, No. 1 038159,

In the accompanying drawings, Figure 1 isa longitudinal section of avalve n1echa nisin embodying the invention a portion thereof being shownin elevation. Fig. 2 15 a longitudinal section taken at right angles toFig. 1. Figs. 3 and t are cross sect-ions taken on lines 33 and +l-'1,respectively, of Fig. 1.

, Referring tothe drawings, designates the. valve casing having thediametrically opposite inlet and outlet ports 3 and et, rerpectively.The casing is or" general cylindrical form with an optt sideor end 2closed hy the screw closure or plug 5. At its opposi e side the casingis contracted to form the tubular threaded extension (5 which isadapledto he serured in the wall of a stand holler or other water c ntainer. A

The opposite transverse walls 5) and 10 Within casin; 3 formthcrcbetween a depression or ravitv l1 \vhicl at one. end is pen toward('luflllt' 3, and at its opposite end connnunl lrs \vith lluhollowinterior '3' o! the casing; cntcnsion '1. The portion of cmitv ll and lin 'ihe plane of ports 5 'parts readily accessible; also to adapt therounded or enlarged centrally at 11 and secured therein is the cup-like.holder 12, with inlet port in open connnunicatiou with one sidothereot'through wall 3, as indicated at 3. The open end of holder 12 facing end2' of the casing is closed by the plug-like valve seat 13, ported at123. A valve ll is confined within holde 12 and is adapted to he movedtoward closed position by coiled spring 15. A stem 1% projects from thevalve through a central aperture in seat- 13, and this stem, togetherwith asimilar stenrl5 and guide 15 at the opposite face of the valve,iuaintaii'i the valve in proper position and insure accurate movementthereof.

For transmitting movement from the thermostat to the spring-closed valve14: a forked support 16 is fitted and movable in cavity 11, the centralstein-like portion 1'? of the support fitting cavity 6 of. the casingextension 6. The opposite side arms 16 of the support embrace the valveholder 19 being movable in the side extensions 11 of cavity 1 l. Stein1? is "hollow and con-- fined therein is spring 1!) which bears againstthe closed end of valve holder 12 and. opposes movement of the support16 imparted thereto by the thermostatic ele ment 8. r

The cooperating movementeompounding levers 20 are i'ulcrunied to theopposite supportarms 18 with the innermost lever engagingvalve stein1 1. An adjustable ahutinent for the outermost ieve'rleonsists of thestem 21 which is threaded through a central aperture in the casing cap5, and at its inner extremity provided with the leverengaging; steelhearing point 212" Secured to stem 21. by nut 22 is a cap 23 W bracesand is rotatable relatively to the easing end 2, said cap thuscomprising a hand hold for adjusting the stern 21 to-the teni; pcraturewhich the valve is to maintain, for this purposethe eap being providedwith a pointer 24- which cooperates with a scale 25 on casing 2, as in.the Patent No. 1,038,159.

The parts are assembled by first introdue ing support 16 into the casingcavity 11 and its side extensions 11", and then with spring 19 in placein the support stem 17 the cup-like valve holder 12 is inserted in' iiehenrahove mentioned teem? hing: havinn) inlet- :tncloutlet 3mg in-- h onea valve \Vllllin the mvity for eontrollin ermmninieation het veen thecasing ports o0- ilililzl'illlgfllll illill-CfllllpOlllldlllg leverswith ono of snitl levers vaoaplecl to transmit movement the valve onabutment. )2? another i '3 tlevice sperm-- i.
